[0024] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments (for the convenience of description and understanding, the following is a schematic diagram of the embodiment of the present invention). Figure 1 Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0025] Example 1: Please refer to Figure 1-4 , the present invention provides a technical solution: a pressure feedback mattress, comprising a latex layer 1, a pressure sensor rubber plate 2 and a palm hard plate 3, the latex layer 1 is a latex cushion of 3 to 5 cm, the thickness of the palm hard plate 3 is 3 to 5 cm, the latex layer 1 is an upper layer, the pressure sensor rubber plate 2 is a middle layer, and the palm hard plate 3 is a lower layer;

[0026] A plurality of pressure sensors 8 are evenly distributed on the pressure sensor rubber plate 2 according to the parts of the human body;

[0027] The palm hard board 3 includes a vibration motor 5 and a vibration plate 4. The vibration motor 4 is arranged on one side of the vibration plate 4. The vibration motor 4 drives the vibration plate 4 to vibrate, thereby vibrating to remind the patient.

[0028] The output end of the pressure sensor 2 is electrically connected to the input end of the central control device 6 , and the output end of the central control device 6 is electrically connected to the input end of the vibration motor 5 .

[0029] Since the injured parts of patients are generally concentrated in the lower part, the vibration plate 4 is arranged in the lower middle part of the palm hard plate 3 .

[0030] In order to improve the air permeability of the mattress, the latex layer 1 , the pressure sensing rubber plate 2 and the palm hard plate 3 are all provided with air holes 7 , and the air holes 7 on the palm hard plate 3 penetrate the vibration plate 4 .

[0031] like Figure 5A feedback method of a pressure feedback mattress: when a patient lies on the mattress, the pressure sensor 8 will display the current pressure of various parts of the human body, and transmit the pressure information to the central control device 6, which will display the pressure information of various parts of the human body contour in the form of points, and judge the parts of the patient's body that are prone to pressure damage according to the pressure information, and then take corresponding nursing measures to reduce the pressure at this place;

[0032] A normal pressure range is set on the central control device 6. When the pressure value of a part of the human body exceeds the pressure range, the point-shaped pressure information will change from green to red.

[0033] When the pressure value of the patient's compressed part is displayed in red for more than 1 hour, the central control device 6 controls the vibration motor 5 to start, and the vibration motor 5 controls the vibration plate 4 to vibrate, reminding the patient to change body position.

[0034] Preferably, the vibration motor 5 can adjust the vibration amplitude to reduce the pressure on the compressed part, promote blood circulation, and relieve the pressure on the patient's skin.

[0035] After the central control device 6 is turned on, the human body contour diagram composed of the pressure sensors 8 in the pressure sensing rubber plate 2 will be displayed on the screen. When the patient lies on the mattress, the pressure sensor 8 of the patient's part will display the current pressure on the corresponding human body contour diagram. If the pressure is greater than the set alarm value, it will change from green to red. Medical staff or family members can intuitively observe the changes in the pressure of the patient's skin, understand the patient's pressure resistance value, dynamically adjust the pressure value according to the skin changes, or take corresponding nursing measures to reduce the pressure here; when the pressure value of a part lasts for more than 1 hour, it means that the patient has not turned over for 1 hour, and the central control device 6 controls the vibration motor 5 to start, and reminds the medical staff or family members through vibration that they need to adjust the patient's body position and effectively turn the patient over according to the compressed part of the patient; the vibration motor 5 can adjust the strength to reduce the pressure of the compressed part, massage and promote blood circulation.

[0036] This mattress combines breathability, pressure feedback, and vibration reminder massage. It can be connected to the computer at the nurse station through the Internet. Nurses can perform precise skin care based on the feedback data, which helps patients protect and care for their skin and prevent pressure injuries. It can be used for clinical pressure injury research and is also suitable for skin care for patients while they are bedridden at home.

[0037] Embodiment 2: The difference from Embodiment 1 is that the central control device 6 is also connected to an external sound and light alarm. When the pressure value of the patient's compressed part is displayed in red for more than 1 hour, the medical staff or family members are reminded to change the patient's position by lighting up the light and making sounds. The sound and light alarm can intuitively attract the attention of the medical staff or family members.

[0038] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
